SPRING-TOOTH CULTIVATOR.

Be it known that I, ARTiiUR Bummer, a citizen of the United States,residing at Albertville. in the county of Marshall and) Stateof Alabama,have invented a newand u'seiful Spring-Tooth Cultivator the followlngisa specification.

The invention relates to improvementsin spring tooth cultivators.

to provide a simple and inexpensive fender, adapted to bereadily appliedto the beam of a cultivator, and capable ofeflectively shielding theplants and adapted to readily ride over stalks and otherobstructionswithout dragging the same along the ground and tearing upcotton or other plants. 7

A further object of the invention is to provide a tender, adapted,whendesireol, to permit a small quantity of fine soil to'sift through tothe plants.

ith these and other objects in View,

the invention consists in the construction and novel con'ibi'nation ofpartsfh-ereinafter fully described, illustrated in the accompanyingdrawings, and pointed .out in the claims hereto appended; it beingunderstood that various changes in the form, pro'- portlon, size andminor details of construetion, within the scope of the claims, may beresorted to without departing fromthe spirit or sacrificing any. of theadvantages of the invention.

In the drawings :Figure 1 is a. side' elevation of a cultivator,constructed in accordance with this invention. Fig. 2 is a plan view ofthe same. 'Fig. 3 is a perspective View of the fender, the'plates beingreversed. Fig. 4 is 'a sectional view of one side of the tender, theparts being arranged as. shown in Fig. 3.

Like numerals .ofreference designate corresponding parts in all thefigures of the drawings.

In the accompanying drawings in which is illustrated the preferredembodiment of the invention,.1'designates a cultivator beam, equippedat-its rear end with handles 2 and supported at its front portion by agage wheel 3 and'having trout and rear tooth carrying bars 4 and 5-,'extendinglaterally from OIPOSltB sides of its rear portlon. The toothcarrying bars are pivoted to the cultivator beam by vertical bolts(i-and 7, and are adjustable backwardly and forwardly from ISpecification of Letters Patent.

This will permit the fenders to move upwardly and downwardly toenable them to ride over stalks and other obstructions.
